Narrator: Today I want to talk about protecting animals. We often forget how important animals are to our world. They make our world more beautiful and lively. They provide food and medicine for us. They play a role in maintaining the balance of our ecosystem. It’s therefore our duty to protect animals.
Video script
The best way to protect animals is to do what many countries did with whales years ago. When several whale species were hunted near to extinction in the last century, many countries made killing whales against the law. If we make it against the law to hunt endangered animals, populations of these animals will have time to recover.
We must also try to protect animal habitats. Creating protected areas is an effective way to protect animal habitats. Well-planned and well-managed protected areas can ensure that water and food supplies are safe, and can reduce the impact of human activities. There are also things we can do to help protect animal habitats, and even a small action can make a big difference. For example, using less paper may not seem like it would save the animals in the Amazon rainforest. Yet since the loss of animal habitats is partly caused by people cutting down trees in the rainforest, to a certain degree, reducing the need for paper helps protect animal habitats from destruction.
Finally, making people understand the problems facing animals also helps. The more we learn about how human activities harm the environment, the better we’ll be able to change our behaviour—before it’s too late！

Homework
With the development of cities, wildlife’s living areas are becoming smaller and smaller. They not only have little to eat, but also may be killed by human beings. Personally, these species of wildlife are important part of our life. More measures should be taken to protect them from being hurt. To begin with, more laws must be made to stop people from cutting down trees. What’s more, all the factories must clean the waste water before it is poured into rivers or lakes. Last but not least, more reserves should be set up so that wild animals can live safely.
I hope these measures will make us live in harmony with wildlife.
